In Vitro

Pramipexole shows a low binding affinity for D1-type receptor, with an IC₅₀ of >50,000 nM^[1].
? Pramipexole dihydrochloride (0.01-10?μM; 72 hours) produces dose-dependent increases of dendritic arborization and soma size^[3].
? Pramipexole dihydrochloride attenuates levodopa-induced toxicity in mesencephalic cultures, suggests that pramipexole may be cytoprotective to dopamine neurons in tissue culture^[4].

This equation is commonly abbreviated as: C₁V₁ = C₂V₂

In Vivo:

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1
